KAI WILLIAMS: Favorite part of the day? “This really enthusiastic family from Greenport, Long Island, came by and talked to me for awhile. I said they could have this huge 4'x4' piece of scrap, but I guess the guard upstairs stopped them, because I later spied it in the lobby.” Above: Williams attaching the legs to a stool and screwing in the bolts by hand. “Odd, because I thought I used the drill on all of the pieces,” he says.
